<p><b>stereographic</b> is an alternative <a href="Fisheye_Projection.html" title="Fisheye Projection">fisheye Projection</a> which is <i>conformal</i>, making it more
suitable for printing than standard fisheye images which are extremely distorted at the edges.
</p><p>All versions of the <a href="Pano12.html" title="Pano12">pano12</a> library since 2.8.1 have supported this and some other novel <a href="Projections.html" title="Projections">projections</a>.
Various GUI front-ends<a class="external" href="http://wiki.panotools.org/GUI_front-ends">[*]</a> including <a href="Hugin.html" title="Hugin">hugin</a> and PTAssembler<a class="external" href="http://wiki.panotools.org/PTAssembler">[*]</a> now support it directly.

to standard <a href="Fisheye_Projection.html" title="Fisheye Projection">fisheye Projection</a> for these images.
